Benefits of technology

The invention provides a duplex scanning apparatus that improves the efficiency of transmitting documents. The method controlling the sheet-feeding includes steps to increase the speed of each document in the inverting channel, making it faster than the document in the sheet-feeding channel. This results in faster transmission of documents through the duplex scanning apparatus.

Problems solved by technology

However, the process of manually turning over the document is troublesome.

Embodiment Construction

[0054]FIG. 2 is a schematic side view illustrating a duplex scanning apparatus according to an embodiment of the present invention. As shown in FIG. 2, the duplex scanning apparatus 2 comprises a sheet entrance 20, a sheet exit 21, a sheet feeding channel 22, a sheet transfer channel 23, an inverting channel 24, an image reading module 25, a transfer roller assembly 26, a sheet input tray 27, a sheet output tray 28, and a sheet pick-up module 29. The sheet feeding channel 22 is arranged between the sheet entrance 20 and the sheet transfer channel 23. The sheet transfer channel 23 is arranged between the sheet feeding channel 22 and the sheet exit 21. A first end D21 of the inverting channel 24 is connected to the junction between the sheet feeding channel 22 and the sheet transfer channel 23. A second end D22 of the inverting channel 24 is connected to the sheet transfer channel 23. The image reading module 25 is located in the sheet transfer channel 23 for reading the image of a do...

Abstract

A duplex scanning apparatus and a sheet-feeding control method thereof are provided. The duplex scanning apparatus includes a sheet feeding channel, a sheet transfer channel, an inverting channel, and a sheet sensing module. A first end of the inverting channel is connected to a junction between said sheet feeding channel and the sheet transfer channel. A second end of the inverting channel is connected to the sheet transfer channel. A distance between the sheet sensing module and the first end of the inverting channel is greater than a distance between the sheet sensing module and the second end of the inverting channel. When a document is transferred through the sheet sensing module at the second time, a next document is fed into the sheet feeding channel through a sheet entrance.

Description

FIELD OF THE INVENTION[0001]The present invention relates to a duplex scanning apparatus, and more particularly to a duplex scanning apparatus for enhancing the efficiency of transmitting documents.BACKGROUND OF THE INVENTION[0002]Scanning apparatuses are widely used for scanning images of paper documents. Consequently, the contents of the paper documents can be converted into electronic files. The electronic files may be further spread, managed or stored by the user. With the maturity of scanning technologies, the scanning apparatuses have experienced great growth and are now rapidly gaining in popularity. In the early stage, the scanning apparatus can only scan one side of the document. For scanning both sides of the document, after one side of the document has been scanned, the document should be manually turned over so as to scan the other side of the document. However, the process of manually turning over the document is troublesome. For solving the drawbacks, a duplex scanning...
